MASTER OT J064533.25-425126.4 discovery - possible SN in 2.6W 8.9N from PGC556833 (2MASS) galaxy
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 349171 )discovered OT source at (RA, Dec) = 06h 45m 33.25s -42d 51m 26.4s on 2015-12-06.02329 UT.
The OT unfiltered magnitude is 18.0m (the limit is 19.5m).
The OT is seen in 5 images. There is no minor planet at this place. We have reference image without OT on 2015-02-18 21:58:09 UT with 20.6 unfiltered magnitude limit.
This PSN is in 2.6W 8.9N from PGC556833 with B=17.8, I=15.5.
Spectral observations are required.
